<h1>Loading panels on demand</h1>
<p>All the panels of a panel stack can load when the document is executed, 
 even though only one panel is displayed to the user. This ensures that 
 these pre-loaded panels display immediately when the user selects a different 
 panel. However, if the user is unlikely to access all the panels in a 
 panel stack, or if you want to optimize the initial load time of the document, 
 you can specify that the panels load on demand. </p>
<p>When panels are loaded on demand, only one panel is loaded when the 
 document is executed. Other panels are loaded only when the user selects 
 them. The document therefore opens faster, though panels loaded on demand 
 will take some time to load when they are selected. After a panel is loaded, 
 it remains cached on the client until the document is closed.</p>
<p>On-demand panel loading occurs when the document is executed in MicroStrategy 
 Web with DHTML enabled. In Desktop, only the current panel is displayed, 
 selectors are not active, and therefore other panels are not available. 
 On-demand panel loading does not occur in Flash Mode.</p>
<p><span style="font-weight: bold;"><B>Note</B></span>: If your browser supports 
 DHTML, DHTML is enabled in MicroStrategy Web by default. </p>
<p>You can define how panels are loaded at two levels:</p>
<ul>
<li class=p-First-Bullet-Do-Not-Type-Text><p class=First-Bullet-Do-Not-Type-Text>&nbsp;</p></li>
	
<li class=p-Topic-Text-Bulleted><p class=Topic-Text-Bulleted>For all 
 the panel stacks in the document (the document-level setting)</p></li>
	
<li class=p-Topic-Text-Bulleted><p class=Topic-Text-Bulleted>For each 
 panel stack</p></li>
</ul>
<p>This allows you to easily set different panel load settings for different 
 panel stacks. For example, a document contains multiple panel stacks. 
 You want to pre-load all the panels of all the panel stacks, except for 
 the panel stack that contains many panels. At the document level, define 
 the default panel load setting to pre-load all panels. For the specific 
 panel stack, specify that only the current panel is pre-loaded.</p>
<h2>To specify the default panel load setting for all panel stacks in a 
 document</h2>
<p>The document-level setting applies to all panel stacks that use the 
 default panel load setting. You can change the panel load setting for 
 specific panel stacks as well, as described in 
<a href="#To_specify_how_to_load_panels_for_a_specific_panel_stack">To 
 specify how to load panels for a specific panel stack</a>.</p>
